Chapter 23, Problem 45P
Light is incident along the normal to face AB of a prism that has a refractive index n and an angle α = 30°, as shown in Figure 23.54. When the prism is in air, the light undergoes total internal reflection. However, when the prism is immersed in water, a faint refracted ray emerges at an angle of 80° to the normal of face AC. (a) Determine n. (b) What material was used to make the prism?

A flat piece of glass covers the top of a vertical cylinder that is completely filled with water. If a ray of light traveling in the glass is incident on the interface with the water at an angle of θa = 36.2°, the ray refracted into the water makes an angle of 49.8o with the normal to the interface. What is the smallest value of the incident angle ua for which none of the ray refracts into the water?
The indices of refraction for violet light (λ = 400 nm) and red light (= 700 nm) in diamond are 2.46 and 2.41,
respectively. A ray of light traveling through air strikes the diamond surface at an angle of 53.5° to the
normal. Calculate the angular separation between these two colors of light in the refracted ray.
